.collect the oil flowing from the milling cutters on the table andreturn it into a Well or reservoir from which it is supplied to saidcutters.

It consists in certain novel features of construction and in thepeculiar arrangement of parts as hereinafter particularly described andpointed out in the claims.

In the accompanying drawing like characters designate the sameparts inthe several figures.

Figure 1 is a partial side elevation and vertical section on the line 11, Figs. 2 and 3, of a milling machine embodying' the pres entinvention; Fig. 2 is a plan v1ew of the work table; Fig. 3 is a verticalsection of the tableand saddle on the line 3 3, Figs. l and 2; and Fig.4 is a. longitudinal section on the line 4 4, Fig. l of the telescopicoil pipe connecting the saddle with the oil reser- Voir in the frame.

For the purpose of illustration the improvements constituting thepresent invention are shown as embodied in a plain milling machine, butwith slight changes they are equally applicable to universal millingmachines.

Referring to the drawing, a designates the frame or case, which is of:the usual box or closed form. It is provided in the lower part thereofwith an oil reservoir b froln which oil is raised by a pum c through apipe d and delivered to the mllling cut-ter e.

The work table f is formed near the ends with transverse oilintercepting channels g, which lintersect and extend below the bottomsof the usual T grooves or slots h. It is also formed along the frontside with an open longitudinal channel z' running into the transversechannels g, and at the back side with a deeper longitudinal channel y',also running at the ends into the channels g.

Midway between its ends a discharge opening is formed through the bottomof the channel y', which is provided with a short piece of pipe or anipple c extending a short distance below the bottom face of the table.

To exclude chips, shavings or other refuse frompthe channel y' it -iseoveredbelow the top of the table with a removable plate Z, and thetransverse channels g are provided at or below the level of this plateand of the bottoms of the grooves h with removable screens m.

The saddle or table support anon which the table f is mounted and movedby the usual feed screw o, is formed with a channel p below and parallelwith the channel j in the table.

A longitudinally channeled and movable i slide q is fitted into a recessabove the channel p flush with the top face of the saddle. It islprovided midway between its ends with a discharge opening 1' through thebottom into the channel p, and into the channel in its upper side thedischarge pipel or nipple /c projects. The saddle is mounted in theusual manner upon the vertically adjustable knee s, and is adjustedthereon toward and from the frame by the screw t, in the usual manner,the knee being adjusted vertically by the screw u. y

A telescopic pipe n having jointed connections fw with the saddle n andframe a, connects the channel p in the saddle with the oil reservoir bin the frame. The oil reservoir b is provided with a partition or baffleplate m between the intake of the pump c and the connection of the pipen, so that impurities carried with the oil into the reservoir throughsaid pipe will not be taken up by the pump and delivered to the milling4cutter.

As to the collection and return of oil from the work table to thereservoir from which it is supplied to the milling cutter, which are theessential functions of the present invention, the machine operates asfollows: The oil delivered by thepump c to the cutter and flowingtherefrom upon the table f, is caught and conductedby the grooves lt andchannel c' and the cover plate Z of the channel y', upon the screens min the transverse channels g, from which it flows into and through thechannel j below said plate, and

is discharged through the central opening and nipple kfinto thechanneled slide g. In

case the traverse-of the table carries the oil discharge opening thereinbeyond the limits of the saddle on which it is mounted, the nipple lcengaging with the ends of said slide, will carry it along with thetable, thus maintaining' constantcommunlcatlon between the channel inthe slide and the dis' ment of the saddle with the knee and theI lateraladjustment of the saddle on the knee and maintain a constant conduit forthe return of oil from the saddle to the reservoir.

In the application of the system to a universal milling machine thechanneled slide g is mounted in the upper part or section of the saddleor table support, usually called the swivel block, and the channel inthe lower part or section of the saddle into which saidslide dischargesand with which the telescopic pipe o connects, is formed on a. curveconcentric with the swivel center, so as to permit of the angularadjust-ment of the table without interrupting or interfering with thecontinuity of the n oil discharge conduit.

Various changes in the details of construction and arrangement of partsmay be made without departing from the principle and intended scope ofthe invention.
